Question

这是我的.h视图控制器文件：

#import <UIKit/UIKit.h>

@interface ZKGameController : UIViewController

{




IBOutlet UIImageView *PlayerSprite;
IBOutlet UIButton *rightButton;
IBOutlet UIButton *leftButton;

NSTimer *animationTimer;

}


[rightButton addTarget:self action:@selector(startLeftAnimation)     forControlEvents:UIControlEventTouchDown];
[rightButton addTarget:self action:@selector(stopAnimation)   forControlEvents:UIControlEventTouchUpInside];
[rightButton addTarget:self action:@selector(stopAnimation)   forControlEvents:UIControlEventTouchUpOutside];


[leftButton addTarget:self action:@selector(startLeftAnimation)     forControlEvents:UIControlEventTouchDown];
[leftButton addTarget:self action:@selector(stopAnimation)   forControlEvents:UIControlEventTouchUpInside];
[leftButton addTarget:self action:@selector(stopAnimation)   forControlEvents:UIControlEventTouchUpOutside];


- (void)stopAnimation;
- (void)frontBarrelAnimation;
- (void)barrelStartDown;
- (void)startLeftAnimation;
- (void)startRightAnimation;
- (void)animateLeft;
- (void)animateRight;

@end

它给了我关于“leftButton addTarget：self ...”的错误消息，等等等等等等。我搜索了为什么，我找不到任何理由，但它说“预期的标识符或'（'，使用未声明的标识符”self“和”leftButton“和右键相同的东西。

如果有帮助，这是我的.m文件： #import“ZKGameController.h”

@interface ZKGameController ()

@end

@implementation ZKGameController

- (void)startLeftAnimation
{
    animationTimer = [NSTimer scheduledTimerWithTimeInterval:.01 target:self     selector:@selector(animateLeft) userInfo:nil repeats:YES];
}

- (void)startRightAnimation
{

    animationTimer = [NSTimer scheduledTimerWithTimeInterval:.01 target:self     selector:@selector(animateRight) userInfo:nil repeats:YES];
}


- (void)stopAnimation
{
    if(animationTimer != nil)
    {
        [animationTimer invalidate];
        animationTimer = nil;
    }
}

- (void)animateLeft
{
    PlayerSprite.center = CGPointMake(PlayerSprite.center.x - 1, PlayerSprite.center.y);
}

- (void)animateRight
{
    PlayerSprite.center = CGPointMake(PlayerSprite.center.x + 1, PlayerSprite.center.y);
}






- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

/*
#pragma mark - Navigation

// In a storyboard-based application, you will often want to do a little preparation before     navigation
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    // Get the new view controller using [segue destinationViewController].
    // Pass the selected object to the new view controller.
}
*/

@end

我已将所有图片视图和按钮与正确的内容相关联，但它为我提供了这些消息。如果您有任何建议请帮助。

剪切并粘贴，之后将目标调用添加到viewDidLoad方法 [super viewDidLoad];在.m文件

Xcode 5：当我向我的按钮添加动作时，它会给我错误消息
